 Below is a complete list of extensions that are currently available to extend the functionality of the professional hull modeler. These extensions are compiled together with the hull modeler into a single program, ensuring a fast and optimal integration of both software and data.
Note: Some extensions require the presence of other extensions to function properly.

Probabilistic damage stability MSC.216(82) |
 |
 The probabilistic damage stability extension developed by DELFTship BV incorporates both the old rules for damage stability as well as the new harmonized rules, MSC.216(82) that entered into force on January 1st 2009. |

Tank modeling |
|
 The tank modeling extension is used to quickly define tanks and internal volumes which can be used in the intact and damage stability calculations. Tanks and other internal compartments are created as 3D objects and modeled entirely with surfaces, just like the hull shape. In order to be able to create even the most complex shapes, tanks may consist of multiple objects called compartments. |

Crosscurves |
|
 The cross curves of stability provide a means of presenting stability for a wide range of displacements, heeling angles and an initial trim. Since the location of the center of gravity varies with the loading of the ship, it is not practical to calculate the actual righting arm for all conditions of loading. Instead it is assumed that the center of gravity is zero and coincides with the keel. The resulting value is called KN*sin(Ø). |

Intact stability (load cases) |
|
 The intact stability extension of DELFTship™ allows for an unlimited number of load cases. The visual approach to calculating load cases ensures maximum efficiency. Calculated load cases are drawn in 3D showing the resulting draft, trim and heeling angle. The results of the calculation are displayed in a customizable report that can also be exported to a HTML file for use in any word processor or spreadsheet. |

Bending moment and shearforce |
|
Extension used for the calculation of the still water longitudinal bending moment and shear force for a selected load case. The calculations are very accurate and the output of the report can be saved to a HTML file so it can be easily integrated into the stability booklet.

Marpol Oil Outflow MEPC.141(54) |
|
|
 Implementation of the probabilistic oil outflow calculation according to MEPC.141(54). This extension calculates the accidental oil outflow performance ("Oil Spill Index”) of a vessel. Only a few parameters need to be specified by the user. DELFTship automatically identifies small tanks (less than 30 m3) which may be omitted from the calculation.

Max. allowable VCG' calculations |
|
 The max VCG' extension examines each individual criterion from the selected set of stability criteria. The maximum vertical center of gravity for each criterion is calculated for which the criterion still complies. The criterion with the lowest value for the VCG is the limiting criterion for the entire set and the corresponding value is called the limiting/max VCG. This value can be calculated for a range of drafts, trims and wind silhouettes. For each combination the stability curve is generated and the criteria evaluated. |

Dredger extension |
|
|
 The dredger extension is an add-on for the regular intact stability extension of DELFTship™. It can be used to calculate the intact stability of dredgers, but also for other vessels with open cargo holds, like open-top container ships for example.

Critical points |
|
 This extension allows for the input of critical points (e.g. ventilation openings, downflooding points, deck edge points, weathertight openings and tank connections). These points can be tracked in calculations performed by the following extensions:
- Load case extension (intact stability)
- Probabilistic damage stability
- Cross curves extension
- Max. allowable VCG' extension

Inclined hydrostatics |
|
This visualization tool can show the design in any condition including critical points so key events, like for example the deck immersion angle or downflooding angle can easily be visualized. The inclined hydrostatics extension offers the designer a view on the hull under trim and heel. After specifying a displacement, heeling angle and trim this module calculates the corresponding draft and some relevant hydrostatic properties.

On 12 March 2010, Fugro took delivery of a new-build survey vessel, the MV "Fugro Searcher". The high-tech survey vessel was build by the German shipyard Fr. Fassmer GmbH & Co. KG located near Bremen.
